HIRAM H. HERRICK, OF EAST BOSTON, MASSACHUSETTS.

CARPET-SWEEPER.

Specification of Letters Patent No.

To all whom it may concern:

Be it known that I, HIRAM H. HERRICK, of East Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Carpet-Sweepers; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings and to the letters of reference marked thereon.

The nature of my invention consists in the arrangement `and employment of such devices as will be hereinafter fully set forth and described.

To enable others skilled in the art to make and use my invention, I will now describe its construction and operation.

In the drawings Figure (1) is a sectional view. Fig. (2) is a plan view of the top and bottom of the machine.

In Fig. (l) (A) represents an end view 0f the box, which is constructed in two parts, and hinged together as seen in Fig. (2). The lower portion of the box is provided longitudinally through its center with a space of sufficient width to permit the brush to operate advantageously. (E, E) are two pieces of tin, which are secured at an inclined position on each side of this space. Said pieces present a concave surface on the inside of the box; and a convex surface, a little below the bottom of the box, their ends being inclosed to prevent the dust or dirt from escaping, after once being taken in by the brush. The upper sides of the pieces (E, E) also extend somewhat above the inside bottom of the box for the same purpose.

(F) represents the shaft to which the brushes are attached. Said shaft is confined to the upper part of the box, and is'located immediately above the space in the lower portion.

(C) is a small cog wheel secured to the end of shaft (F (B) represents the main or driving wheel, which is constructed so as to resemble a cogwheel placed side by side with a wheel of greater circumference, as fully shown in Fig. (2). These wheels have formerly been constructed of metal, and consequently the noise which they make, has been a source of great 25,332, dated September 6, 1859.

annoyance. To remedy this defect, I propose constructing them of vulcanized india rubber, which entirely overcomes this objection, and which also very materially lightens the machine and renders it less difficult to be operated. In front of the space, and nearly directly opposite the driving wheel is a small wheel for the purpose of supporting that portion of the machine. (g) is also another small wheel or caster, located in the center of the rear end of the box. (71,) represents a piece of tin which covers the Wheel (g) and prevents the dirt from escaping when once deposited in the dust pans. x) represent two grooves in the side of the box. The brushes on shaft (F) at this end are flared out in these grooves; and thus the dirt close to the Walls can be swept up as nicely, as in the middle of the floor.

(7c, 7c) represent partitions whichextendI from side to side, in both the top and the bottom of the box.

(D) is the handle, by which the machine is operated.

'Ihe operation of my machine is as follows: All its parts being constructed and arranged as herein set forth, the machine is placed upon the floor, and by means of the handle it is rolled to and fro over its surface: The brushes being revolved by means of driving-wheel (B) the dust and dirt is deposited in the pans. The room may thus be thoroughly swept, without any inconvenience, arising from the dust.

. I claim- 1. Providing the end of the box with a groove as from m to a1, when the same 'is used in connection with the flaring brush on the end of the shaft F, substantially as, and for the purpose, herein specified.

2. Dividing the box in two parts, and providing each with a partition, dividing the bottom of the box in two parts, through which the brushes protrude, and providing these parts of said bottom with flanges, which hold the dirt, the several parts being connected and arranged together substan-
